Have recovered Windows 8.1 from Windows 10 due to couple of issues: Main irritant was that I could not simply read any articles from any web sources without having to again click into that article since the mouse focus goes somewhere else. Very annoying. Does not happen in either FireFox nor Chrome in Windows 10 and does not happen in MSIE in Windows 8.1.

(fyi: other big problem is that there is no wi-fi in Windows 10 Safemode with Networking. Same problem on 5 different computers running Windows 10.)

I would love to know if anyone else has noticed the mouse focus problem.
